Jughead tries a new restaurant in town run by Darlene, a witch in disguise. She gives him his heart's desire -- a huge junk food meal -- in exchange for his metabolism. Over the next month, Jughead eats like normal, but grows very large. The gang tries to trade Darlene other virtues to get Jughead's metabolism back -- Archie's pure heart, Veronica's status, Betty's compassion -- but Darlene swindles them all. Jughead eventually confides in Sabrina, and the two hatch a plan to get the gang's virtues back.

Archie and Jughead are playing chess with Mr. Lodge's crystal chess set when Jughead accidentally breaks a piece. He knows that Reggie has a similar chess set, but in order to replace the broken piece, Jughead has to do a favor for him. Jughead ends having to do favors for two other girls as well in order to get the needed chess piece.
